interstices less closely rugose, and much more shining. 

 The complete division of the eyes in F. crihrains is 

 remarkable, but is not of sufficient importance to indicate 

 generic separation. 



PhUeosiniis vilis, sp. n. 

 Oblongo-ovalis, subdepressus, piceus, elytris rufescentibus, pro- 

 thorace longitudine pauUo breviore,antice constricto, apice sat late 

 rotundato, dorso punctate, liuea media et plaga in utroque latere 

 la3vibus ; elytris punctato-striatis, interstitiis rugis transversis et 

 setis brevibus uuiseriatim ornatis, in declivitate tuberculatis. 

 Long. 1"5-1"6 mm. 



Mas. Fronte irapressa. 



Oblong oval, somewhat depressed. Head black, rugulose, 

 subnitid, very shortly pubescent ; front ( $ ) with a not sharply- 

 defined circular impression ; front (?) subconvex ; eyes narrow, 

 deeply emarginate : antennce brown-testaceous, the club oval, 

 not elongate. Prothorax rather broader than long, widest at 

 the base and constricted towards the apex, the sides slightly 

 rounded behind and sinuate in front the apex rather broadly 

 and obtusely rounded, the base bisinuate, but scarcely pro- 

 duced backwards in the middle ; surface piceous, lighter at 

 apex, moderately shining, subglabrous, strongly punctured, the 

 median line smooth, subelevated throughout, on either side be- 

 hind the middle is a subelevated impunctate oblong space external 

 to a shallow impression. Scutellum small, rounded, black. 

 Elytra as wide as the prothorax, and fully one-half longer, 

 their basal margins rounded internally, nearly transverse exter- 

 nally, narrowly raised and crenate, the sides parallel, the apex 

 broadly rounded ; surface piceous-red, finely punctate-striate, the 

 interstices narrow, subconvex, with uniseriate very short bristles 

 and transverse raised rugse, weaker at the base, tuberculiform on 

 the declivity (a little moi'e strongly in the male), and absent at the 

 apex of the second interstice, which is smoother and flatter in the 

 male. Underside piceous, moderately strongly punctured ; legs 

 brown, the 3rd tarsal joint simple. 



Hah. Sumatra, from tobacco (Grouvelle). 



I have received, from the same source, four or five 

 specimens of this insect, one of the smallest species of 

 the genus and of the Hylesinides. It is unusual in the 

 genus to meet with so little sexual difference in the 

 structure of the elytral apex.
